asp.net, vb - how to format number in unbound gridview

In a asp.net page, I'm populating a GridView in code by filling a DataSet, then binding the GridView's DataSource property to the DataSet (using SQL).

Some of my number columns need to be displayed using 2 decimal places.

In my sql query I made sure I rounded my numbers displayed 2 decimal places (Round(field, 2, 1)).

But when I run my code, 4 decimal places are shown.

So, how do I format numbers in an unbound gridview (in asp.net, vb) to show 2 decimal places?

Try something like this:

        Dim myFieldData As String = "10.3234"
        Dim strText As String = CDbl(myFieldData).ToString("#.00")

Open in new window

The problem is that those columns are numeric in the dataset and when displayed in the datagrid it uses that funny format.

Option 1: In your SQL Query, CAST the column into a varchar... check this: SELECT CAST(CAST(123.4556 AS decimal(6,2)) AS varchar). That way, in the dataset, the column is of string type and will be presented 'as is'

Option 2: Loop through the columns after databinding and perhaps call a function that formats the columns individually.. something like:

private string setFormating(DataColumn bc)
    {
      string dataType = null;
      switch(bc.DataType.ToString())      
      {      
        case "System.Int32":  
          dataType = "{0:#,###}";
         break;                
        case "System.Decimal":            
          dataType =  "{0:c}";
          break;
        case "System.DateTime":
         dataType="{0:dd-mm-yyyy}";
         break;
        case "System.String":
          dataType="";
          break;
        default:    
          dataType = "";
          break;      
      }
      return dataType;
    }
